It's worth about ten cents! DON'T BUY IT!
It works well enough, but the battery is dead EVERY time I try to use it. At first, I thought that it had perhaps rested on the button, turning it on while I wasn't using it. Finally I tried storing it in a little hard plastic box. Still, the battery goes dead in less than two weeks. Pay a little more for a better tire gauge, and save big on batteries!
